This app is built around the idea of having one drink roughly an hour to enjoy the buzz an alcoholic beverage gives you and at the same time not getting drunk. The app lets the user select three levels - small drink, medium and big (coresponding to 30 minutes, 45 minutes and 60 minutes respectively) and then starts a countdown until a next drink. It sends a local notification at 75% until countdown to inform the users its not yet a good idea to have a drink, but soon and finally sends a local notification when countdown is down at zero to inform the user that if they want another drink then its OK already.
Disclaimer: This app should not be used in any way to determine if the user will be able to drive, operate any machine and/or perform any task that requires the user to be sober.
